Ingredients You’ll Need

To whip up this easy fudge, gather:

  • 1 cup unsalted butter

  • 1½ cups creamy peanut butter

  • 2 teaspoons vanilla extract

  • 3¼ cups powdered sugar

  • 1 tablespoon water (to help hold parchment paper in place)

  • Optional: red and green M&M’s, for a festive topping

Pro Tip: Stick with smooth, commercial peanut butter. Natural peanut butter tends to separate and won’t give you that silky, melt-in-your-mouth texture.

Variations & Substitutions

  • Peanut Butter: Jif, Skippy, Peter Pan, or Reese’s all work. Each brand gives slightly different color and sweetness, but the texture stays the same.

  • Vanilla Extract: Out of vanilla? Use maple syrup for a subtle twist.

  • Powdered Sugar: Also called icing sugar or confectioner’s sugar. If you don’t have any, you can substitute granulated sugar, but your fudge may turn out slightly grainier.

  • Toppings: M&M’s make it fun and festive, but chocolate chips, peanut butter chips, or mini marshmallows are also delicious.

    Step-By-Step Instructions

    STEP ONE: Line an 8×8-inch baking dish with parchment paper. Leave an overhang on two sides so you can lift the fudge out later. Add 1 tablespoon of water under the parchment to help it stick.

    STEP TWO: In a large microwave-safe bowl, add butter and peanut butter. Heat for 1 minute, then stir until smooth. Microwave for another 30 seconds if needed.

    STEP THREE: Stir in vanilla extract.

    STEP FOUR: Gradually add powdered sugar, one cup at a time, stirring well after each addition. The mixture will thicken as you go.

    STEP FIVE: Spread the fudge evenly into the prepared pan.

    STEP SIX: Place another piece of parchment paper on top and press gently to smooth the surface. Chill in the refrigerator for at least 2 hours.

    STEP SEVEN: Remove from the fridge, take off the top parchment, and use the overhang to lift the fudge out of the pan.

    STEP EIGHT: Warm a sharp knife under hot water, dry it, and cut into small squares. Add M&M’s on top for a colorful holiday touch, if desired.

    FAQs

    Yes, it sets best and keeps longer when chilled.
  • Can I use natural peanut butter?
    Not recommended — the oil separation will prevent the fudge from setting smoothly.
